If you want to eliminate all spaces, you can use String#gsub.

" a b c “.gsub(” ", “”) #=> “abc”

However, if you want to eliminate leading and trailing spaces and collapse several internal spaces to one, you can combine String#squeeze and String#strip.

" a b c ".squeeze.strip #=> “a b c”

Thanks of the tip on #squeeze Craig! I didn't know about that method.
